Can't login to Cyberpanel, but it's running

For this issue You can check the 2nd Step remove the Kingsing. If you have ssh access then try removing and then kill all the processes using too many resource. And then restart lsws and lscpd then reboot your system. You system should be perfect.

And I strongly believe the problem is because of the malware.

If you would love to explore you can try this otherwise if you have backup then restore it.
